Referring more particularly to the acc.om.

11, olf-a vertically positioned vpneuinaticdisfpatch-tube' andare received into: a receiving. l tube,12, Ipositioned below,` andv forming a -fcontinuation of' fthe discharge tube4 Thee has a correspondingly slightly inclined bot-V tom or stop 16. The lower front portion of the' receiving tube is providedwith an open- 'ing or cut away portion, 18, through which the carrier 1() may be -readily removed by the operator.

If carriers should bediscliarged through the tube, 11, at a rate greater than they can be accepted'aiid disposed of by the operator, some of the carriers will be stopped in the upperportion of the receiving tube,.12, by unreinoved carriers in the lower;portion thereof. "These carriers are therefore permitted to fall through, or are deflected through,- an opening, 20, in the rear of the receiving tube above the lower opening, 18, and. of a size suflicient topermit the carriers to droptherethrough. The inclined position of the carrier resting on the curved or inclined portion 14: of the receiving tube and the base or stop 16 may assist the deflection of the succeeding carriers through the opening 20.

:At certain periods,'there is ordinarily no overflow of carriers and no reserve operator 1s accordingly required. To avoid the passage of carriers to the position occupied by a reserve operator, in. case two carriers should be discharged in close succession and both reach the receiving tube 12 before the former of them is removed, a guard or retainer is provided which maybe moved in-v t0 position to positively prevent the passage of carriers through the opening 20. This retainer or guard may be'of any suitable form. A preferred embodiment shown in the accompanying drawing comprises a ring or collar 22 mounted on the discharge tube 11 and provided with a downwardly eXtend-` ing finger 211. The lower edge ofthe ring or collar 22 is Supported on acollar 26 connecting the receiving tube 12 to the discharge tube 11 and is rotatable about the tube 11 with slight friction to permit the finger 24to be moved directly back: of the opening 20, to prevent'the passage of carriers:therethrough, orto aposition at the side ofthe receiver'to permit the ready discharge of carriers.

It is sometimes convenient-to permit the operator to` deflect all of the carriers discharged from the tube 11 to the reserve operator and leave the operators desk free from the necessity of accepting and disposing of carriers. To thisend a defiecting slide 28 is provided opposite the opening 20 in such a manner that it may be inserted into the receiving tube 12 to prevent the passage of carriers to the lower portion of the tube `and to deflect themY through the opening 20. The deflecting plate 28 is preferably formed of a triangular shapeand has a slid-g` ing pivotal connection to the tube 12, by

means of which it may be lifted and swung and out of the receiver tube andheldhSecurely in eitherjposition. c The `defiectbr plate is held or retained .in deflectingposition in the receiver 12 bymeans of` a notch"` 38 in the lower edge of the plate which en-` gages an edge or projection 4() formedon the receiver tube by the lower end` of the slot 30. The deflector is held out ofthe` re ceivingtube by means of a notch42 inwthe lower cornerof the plate, which in the withdrawn position' of the deiector, engages the projection or latchflO.

The operation of the invention is briefly as' follows: i

Carriers are normally `discharged through the tube 11 to the lower part 14 of the re-7` ceiving tube 12from which they, are removed by anoperator having chargerof the;

receiver. carriers are discharged, these carriers are deliected bythe presence ofa carrier in the When an overflow or excess ofA receiving portioirlli through an` opening 20 and pass toa reserve operator.` In case no reserve operator isprovided and the normal supply of carriers isreceived attemporarily` varying rates, the guard or retaineiy` 24is.

moved to position .backY of the openngZO To pass all the carriers anytime to there serveoperator, the

of the receiver 2 to the lower part ofthe opening 20. The carriers discharged pass` directly toa reserve operator or may be de' Guard or retainer n24; is. moved to the side ofthereceivin' tubeand 4and all carriers discharged throughthetube i. 11 are retained in the receiver until removed. i

liveredto a reserve operator by any suitable y carrying or conveying means as shown...

beieinbodied in other formsthanthat shown VIt will be obvious that the invention mayV in the above specification anddrawingsand y that theiforin of embodiment may varied in adapting it to different conditions or cir` `cumstances, without departing, bfrom the broader features of the invention.

Having described the ,.invention, what claimed as new, is: y .y yx, 1. The combination, with a pneumatic dispatch apparatus, of a tubular receiver hav J ing a lower carrierreceiving,portion andan be` re-` moved tlierefromand anopening a ovesaid Areceiving portion thru which vcarriers opening thru which carriers fina be discharged when said receiving portion is occupied. y

2. The combination, with a discharge tube of a pneumatic dispatch apparatus, of a receiver having upper and lower openings, means for deflecting carriers through said upper opening at the will of the operator and a guard movable into position to pre- Y vent the passage of carriers through said upper opening.

3. The combination, with a discharge tube of a pneumatic dispatch apparatus, of a receiver having upper and lower openings, a guard movable into and out of position to prevent passage of carriers through said upper opening, said guard being supported by means of a rotatably, sliding collar.

4. The combination, with the discharge tube of a pneumatic dispatch apparatus, of a receiver having upper and lower openings and a guard rotatable about said receiver to obstruct or free said upper opening.

5. The combination, with a carrier discharge tube of a pneumatic dispatch apparatus, of a receiver having upper and lower openings and a deiiector plate arranged in one position to provide a delecting guard extending downwardly and rearwardly in said receiver at the lower portion of said upper opening to deiect carriers outwardly through said opening, said deflecto'r plate being movable from said position to a position such that it no longer deflects carriers through the upper opening.

l6. The combination, with a discharge tube of a pneumatic dispatch apparatus, of a receiver having upper and lower openings, a triangular plate having a sliding and pivotal connection to said receiver, notches at its lower edge, a co-operating slot in said receiver whereby one face of said plate may be held adjacent the forward face of said receiver or inclined downwardly toward the lower end of said upper opening.

7 A tube-shaped receiver for a pneumatic dispatch apparatus having a lower rear portion inclined forwardly and downwardly and the front portion adjacent thereto being cut away to permit the easy removal of a carrier and an opening in the rear of said receiver above said inclined and cut away portions to permit carriers to pass therethrough.
